Why this movie was not an enormous hit when it was released in 1986 is beyond me.
It has a fantastic cast - Alan Alda, Michael Caine, Bob Hoskins etc., etc., and a great story.
In brief, Alan Alda is a High School teacher who writes a book about his New England town during the Revolutionary Wars and then sells the rights to a movie company.
The film makers then descend on the town en-masse to make the movie where the story actually happened.
Bob Hoskins is the screen writer constantly at odds with Alan Alda over changes to his story.
Michael Caine is the English actor hired to play the big bad Redcoat Officer and completely steals the picture.
Watch out for the daily swordfight between Caine and Alda. It is hillarious.
One of Michael Caine's best and definately Alda's best since M*A*S*H.
Buy and enjoy.
